Golf Club Grip {A Golf-Club Grip}

The present invention relates to the grip of a golf club with seizable marks that allow golfers to build accurate golf swings based on golf science and that can be applied to drivers, spoons, irons, and putters. . The use of the present invention eliminates undesirable grip poses that may occur with the grip of a conventional golf club and results in institutionally accurate and powerful swing motions. For this reason, the invention of the patent is suitable for the grip of golf clubs for irons and drivers requiring distance as well as for putters requiring accuracy.

In recent years, golf is becoming popular due to the change in the standard of living and the perception of golf in the world. As the level of the game rises, golf becomes even more exciting. To enjoy golf, you need to know golf science first of all. Golf science is made up of hardware, golf equipment, and software, golf mechanics, both of which are closely connected.

Golf science is a science that provides a variety of theories necessary to improve golf equipment and golf swing in order to achieve accurate and powerful hits. More specifically, the ball's elasticity and dimple effect, the aerodynamic trajectory change according to the spin type and rotation rate, the swing dynamics of the golf club, the repulsion coefficient of the driver head, the elasticity and flex of the shaft, the swing weight, the moment of inertia, and the address posture A comprehensive study of organically related knowledge of chemical engineering, fluid mechanics, physics, dynamics, structural mechanics, and material engineering, which can explain the causal functional relationship between ball and external forces and ballistics in relation to swings and swing methods. It can be called science.

The golf club, along with the ball, forms the center of the golf equipment and consists of a driver, spoon, iron and putter, each of which consists of three parts: the clubhead, the shaft and the grip. For example, club heads have developed new alloy materials, such as titanium, which are lighter and more resilient, and leading companies are remarketing expensive driver models that are lighter and more resilient every two to three years. Released on. In the shaft, drivers and iron golf clubs emerged with carbon composites, which had been rejected by previous steel shafts, and had a light weight and large flex. In contrast, the grip has not yet seen a material or functional design innovation comparable to that of the driver head or composite shaft.

Not many people realize that the rubber grip design of the club is just as important to the performance of a golf game as it is to the club's head or shaft. Observing golf clubs on the market, there are many cylindrical rubber grips on drivers and irons, and round rubber grips on the back and flat on the back. However, this conventional cylindrical grip, which has no characteristic in the longitudinal direction of the grip, makes it difficult to coordinate the small amount of club movement that must occur properly in both hands during the backswing and forward swing. For example, if the grip is too loose, the weight of the clubhead causes the grip to play in the right hand during the backswing and slices at impact. If the grip is too strong, the grip of the wrist outside of the hand instead of the grip movement in the hand. Caulking is disturbed, making a hook. More detailed description of the above error is as follows. In general, novice golfers have no choice but to hold the grip hard to counter the weight of the pole during the swing and maintain the desired swing trajectory. The contradiction of golf is that the stronger the grip, the stronger the swing arm is. It is long and difficult to handle twisting, and trying to prevent twisting of both arms leads to a batting bat. On the contrary, when the grip is gripped gently, the caulking of both wrists taken at the address due to the weight of the clubhead causes less grip, and the grip is played in the hand, causing the slice. In other words, too strong or too weak grips do not serve as a proper link between the body and the club shaft swing, and if the grip strength is not tuned, even the swing will be distracted.

Therefore, in order to improve performance, a grip design is urgently required to guide and maintain a small amount of relative rotational movement of the club in the right direction during the swing regardless of the strength of the grip in both hands.

The present invention has been made to solve the above problems, and provided with a cover that rotates freely on the grip can not only guide the backswing in a consistent posture, but also in the forward swing to coordinate the swing of the body to swing the club It relates to a golf club and a grip capable of resonating, which produces a concise and powerful swing. Since the present invention can be used in all club grips such as drivers, spoons, irons, putters, and the like, the golf scores can be used to improve the overall golf score.

In order to achieve the above object, the present invention is provided with a pair of markers on the grip of the club to allow a relatively smooth rotational movement between the right hand of the golfer holding the club and the club, the pair of markers are both ends of the pin shaft through the shaft In addition, the cover pair is installed in the position where the thumb and hook-shaped index finger of the right hand grasps the grip to facilitate a small amount of relative rotational movement between the club and the right hand of the golfer holding the club. The pin shaft connecting the marker pairs is installed parallel to the striking surface which is the face of the club head and perpendicular to the central axis of the shaft. Here, the pair of markers are integrally provided at both ends of the pin penetrating the hole processed in the grip and the shaft body, it characterized in that it is free to rotate with the pin.

In addition, the pin is inserted into a bushing penetrating a hole formed in the grip and the shaft body, it is characterized in that the body can be freely rotated as one body with the pair of markers provided on both ends of the pin.

In addition, the marker pair includes a thrust bearing (thrust bearing) provided on both ends of the fixed shaft that does not rotate, the indicator is connected to the thrust bearing to be rotatable; Alternatively, the cover pair may include a journal bearing provided at both ends of the fixed shaft that does not rotate, and the cover is connected to the journal bearing to enable rotation.

In addition, the marker pair may be attached to the rubber grip or shaft body directly by an adhesive or a screw directly and freely rotated, and the marker pair may be attached to the surface of the grip by an adhesive means; And a thrust bearing having the bearing support as a part, wherein the mark of the pair of marks is rotatable by the thrust bearing. Or a pair of bearing supports attached to the surface of the grip by an adhesive means; And a journal bearing having one shaft attached to the bearing support, wherein the mark of the pair of markers is rotatable attached to the other shaft of the journal bearing.

In addition, the label pair is directly attached to the rubber grip and the shaft body by an adhesive or a screw, it is characterized in that it has the effect of rotating by the sliding action of the surface.

On the other hand, as another aspect of the present invention is characterized in that the pair of markers are attached on the ring as an auxiliary tool, the ring is attached to the grip of the golf club again. At this time, the ring is in a loose state is fixed so as not to move when the grip is fitted, the inner ring of the ring is characterized in that it comprises a plurality of small non-slip projections having a sharp end. The ring is loose before attaching and is tightly tightened when attached to the grip.

In addition, the cover of the cover pair is characterized in that it comprises a plurality of cover pairs up and down on the grip, the cover pair may be round and convex in the shape of a button, or may have a concave round cavity (cavity). And it is preferable that the cavity further comprises a filler of a soft material.

Here, the material of the label is advantageously made of metal or plastic.

On the other hand, as another aspect of the present invention, the present invention is to set the virtual pin axis in place of the actual pin axis, even if there is no label on the front end of the virtual pin axis attached to the actual pin axis (not shown) In the front end, the front cover slides against the thumb, and in the rear end, there is a sliding action between the hook-shaped index finger and the grip surface to provide a grip having the same effect as having a pair of markers.

In the present invention, in order to technically firmly secure the rotation axis of the first pendulum motion, which was ambiguous in the conventional golf club 2, the pin shaft is in contact with the thumb and hook-shaped index finger of the right hand on the grip 400 of the club 2. 100 may be made and rotated freely at each end thereof, otherwise, a pair of bevels 200 having a smooth surface are fastened. The presence of the marker pair 1 on the grip 400 of the golf club 2 reminds the golfer that the pin 100 of the marker 200 is the center of rotation of the first vibration system. Since the pin axis 270 is perpendicular to the target line parallel to the striking surface 710 of the club, the swing including the first vibration centered on the pin axis 270 held by the right hand of the right hand is always accurate. . If you make the first vibration of the club shaft through the pin shaft 100 in the backswing, the second vibration of both arms around the cervical spine, and the third vibration of the spine around the hip bone, the forward swing will cause the three vibrometers to reverse. The resonance between the chains occurs, and the batting is accurate, the flying distance is increased, and the swing form is also improved.

1 is a perspective view showing the grip of a golf club having a pair of markers of the present invention, Figure 2 is a perspective view of the golf club viewed from the golfer side, Figure 3 is a golf club grip method of the present invention It is a perspective view explaining the procedure. 4 to 11 show the first and eighth embodiments of the present invention, showing a grip cutaway view of a pair of markers provided with pins, bushings, thrust bearings, journal bearings, and the like.

First, the grip of the golf club provided with the pin 100 and the cover pair 1 of this invention is demonstrated using FIG.

The present invention allows a relative rotational movement between the skin of the gripping finger and the club 2 to occur at the middle and lower portions of the grip 400, precisely the right hand index finger, in a conventional golf club 2. It is characterized by including the cover pair (1) up and down. The cover pair 1 is attached to both ends of the pin 100 coupled to penetrate the grip 400 and is provided to be rotatable. The pin 100 is preferably perpendicular to the shaft central axis 550 of the club 2 and parallel to the face of the club head, with the right hand thumb and hook at both ends of the pin 100. A pair of rotary marks (200, freely rotated) are attached to the shape that can be grasped by the) -type detection grip. If there is a pin 100, the diameter of the pin is, for example, about 3 to 5 mm, and the mark fastened to both ends of the pin is a convex, for example, button shape having a diameter of 10 to 15 mm higher than the grip surface, It can rotate with the pin or rotate relative to the pin. In the absence of a pin, a rotatable convex button-shaped pair of labels is attached to both ends of the virtual pin, or a non-rotating but-built cover pair is attached. The height of the cover can be minus height as well as the plus height, and a pair of cover cavities in the shape of a circular cavity recessed under the grip may be provided at the positions of both ends of the virtual pins. The circular cavity-shaped cover may be left at a negative height, but the grip surface may be flat by filling a hole with a soft material such as cotton or sponge. Only the edge and inside of the hole is hard, so you can feel its presence with your thumb and hook-shaped index finger.

(Example 1)

First, the first embodiment of the present invention will be described in detail with reference to FIG. 4. Figure 4a shows a cutaway view of the grip structure in which the pair of markers 1 are fastened to the pin 100 in one body and are inserted into the holes in the grip and shaft body to rotate together. 4b shows a grip structure in which a bushing 300 is inserted into a hole through a grip and a shaft, and a pin pair is inserted into the bushing so that the pair of pins 1 are fastened to both ends thereof so that the pin can rotate better in the hole. The cut cross section of is shown. When holding the two hands (3) by interlocking or overlapping the grip with the thumb and hook-shaped index finger with the right hand grip, the diameter 3 to penetrate the grip 400 and the shaft 500 to the area where the index finger touches. Drill a hole of about 5 mm, the pin 100 is inserted directly into the hole, or the bushing 300 containing the pin 100 is inserted, for example, 10 to 15 mm in diameter at both ends of the pin shaft Fit a pair of cover 200 with a curved surface about to fit.

The surface shape of the cover 200 can be any of convex on the grip, concave below the grip, and smooth as the surface of the grip. The cross section of the label is preferably circular, but is not limited thereto. The size of the cover 200 is, for example, is considered suitable if the height or depth of about 2 to 5mm, the diameter of about 10 to 15mm, but the size is of course not limited thereto. Also, the pins connecting the marker pairs may actually exist or be virtual axes. It is important to feel the presence of the pair of markers through the thumb and hook indexes of the right hand while the golfer is holding, and smooth relative rotation between the golf club and the two hands (3), especially the right hand, which is held by the golfer should be allowed. As long as this is satisfied, there is no limitation on the structure of the cover 200 or the shaft 100.

If the material of the cover 200 is convex, any material can be used as long as it is a hard and smooth material such as metal or plastic that does not rust. In the case of concave, it is better to protect the edge surface of the cavity with a thin metal or plastic plate.

1, 2 and 4 to describe in more detail, the installation position of the pin 100 is installed in the position where the index finger of the thumb and hook (hook) contact in the grip of the right hand, the shaft 500 ) Must be perpendicular to the central axis and parallel to the club face 710.

(Example 2)

A second embodiment of the label pair 1 using a thrust bearing 150 will be described in detail with reference to FIG. 5A. To induce the rotational movement of the marker pair 1 for the same purpose as the first embodiment, the pin is fixed in the hole, and the thrust bearing 150 is used to allow free rotation of the marker pair 1. Figure 5b shows an enlarged view of the attachment portion of the cover 200 on one side.

(Example 3)

6 shows that the thrust bearing 150 used in the second embodiment is replaced by the journal bearing 310. The fixed shaft 110 penetrating the hole in the grip and shaft 500 is fitted to the inner diameter of the journal bearing 310 and the cover 200 is fitted to the outer diameter of the journal bearing 310 so that the two are relatively relative to each other. It can rotate freely. The third embodiment means that any bearing can be adopted as long as the rotational movement of the marker 200 is facilitated in the present invention.

(Example 4)

Next, the label pair 1 attached to the independent thrust bearing 150 without a pin will be described with reference to FIG. 7. Punching the grip and shaft results in a drop in the material strength of the club, unless a reinforcement is installed around the hole, so that FIG. 7 shows a thrust bearing 150 without a pin or a fixed shaft 110 in the second embodiment. Only the separation is shown an embodiment attached independently using an adhesive means such as an adhesive on the grip 400. That is, the bearing support 250 of the thrust bearing 150 is attached to the grip 400 or the shaft body 500 by an adhesive means, and the mark 200 may be independently rotated through the bearing. In this case, the axis connecting the pair of markers becomes a virtual axis, not an actual axis. However, since the pair of markers is installed at both ends of the pin, the virtual axis can perform the same role as the actual axis. According to the embodiment configured as described above, the rotary indicator pair 1 may be implemented in a more secure and simple structure.

(Example 5)

FIG. 8 corresponds to the case where the independent thrust bearing without the fixed shaft 110 is replaced with the independent journal bearing in the fourth embodiment. In this case, the shaft of the inner diameter of the journal bearing 310 is integrally formed with the bearing support 250, and the cover 200 of the button shape is fitted to the outer diameter, and the underside of the bearing support 250 is grip 400 or the shaft. The body 500 is fastened by the adhesive means. Even in this case, the cover 200 can be rotated alone, and the axis connecting the cover 200 becomes an imaginary axis rather than a real one.

(Example 6)

As shown in FIG. 9, the pair of markers 1 may be configured as a built-in marker 200 which is directly attached to the grip or the shaft body. However, since the cover 200 is fixed to the grip 400 by screwing or adhesive coupling, it is necessary to have a smooth surface in order to reduce friction in the rotational movement between the right grip finger and the club. In FIG. 9, instead of the mark 200 attached to the rotatable bearing shown in FIG. 5 or FIG. 6, a non-rotating stationary mark 200 having a smooth surface in place may be attached by screwing or bonding means. Shows that it can. The fixed cover pair 1 may also have the same effect as the rotating cover pair 1, which is a smoothly treated surface of the cover 200 and the skin of the right thumb and hook-shaped index finger that grasp the cover 200. This is because slippage in the rotational direction occurs between the cover 200 to exert an effect as if the cover 200 is rotated. Therefore, even in this case, the virtual pin axis 270 connecting the marker pair 1 can serve as the pin of the club 2 rotational movement. In such a configuration, unlike the first to fifth embodiments, subsidiary materials such as the bushing 300 or the bearings 150 and 310 are unnecessary, and the adhesive strength of the club shaft does not impair the structural strength of the club shaft. Therefore, while maintaining the same effect, it is advantageous in terms of preservation of structure strength, manufacturability and cost reduction.

(Example 7)

As shown in FIG. 10, the rubber grip 400 as a ready-made product, which is pre-molded with the pair of markers 1 at the right hand grip position to be fitted to the club shaft 500, may also perform the function of the present invention. The ready-made grip 400 having the structure of such a pair of markers is also within the protection scope of the present invention as long as it helps to smooth the relative rotation between the two-hand grip and the club 2.

On the other hand, the ready-made grip which shape | molded the downward recessed cavity which is a negative height instead of the positive height convex cover may be sufficient (not shown). Thus, instead of the up-convex cover 200 shown in the figure of FIG. 10, ready-made rubber grips formed with a hollow cavity which is dug down are also included in the technique of the present invention. Holding the grip so that the index finger grip of the right hand falls on the circular cavity pair, the slip naturally occurs between the index finger and the edge of the cavity, and the cover 200 rotates, and the cover pair 1 is connected. This is because the virtual axis 270 is parallel to the club face and can be fitted to the shaft such that it is perpendicular to the shaft center axis to serve as a central axis of rotational motion.

The pair of markers (1) is usually installed in the middle of the grip of the driver, spoon, and long iron, but in the short game clubs such as sand wedge pitching wedge putter, a plurality of, for example, two pairs of markers are relatively close. It can also be installed on the street. This is to allow tall golfers and short golfers to be considered together, or to approach relatively long distances as well as relatively close to the approach.

(Example 8)

In the eighth embodiment, in addition to the cover pairs which have been post-processed on the existing clubs or ready-made grips which are molded and sold at all, the cover is easily detachable to the existing clubs 2 and has excellent practicality as shown in FIG. It also shows that the ring as a ready-made preformed pair 1 is also within the technical protection scope of the present invention. The ring shown in Figure 11 is shown only for the cover pair (1) attached to the built-in smooth surface, but instead of the fixed cover is provided with a trust bearing 150 or journal bearing 310 can be rotated itself Rings with attached label pairs are also a feature of the invention. Since the ring 600 can be easily attached to and detached from the grip 400, the ring 600 may be moved up and down. The width of the ring 600 may be, for example, about 20 mm, but is not limited thereto. The structure of the ring 600 is, for example, open before attachment, and when grip is attached, a grip 400 is used by using a small screw or other fastening means. ) May be tightened or secured over the On the other hand, the inner surface of the ring 600 is provided with a small projection (not shown) with a sharp tip so that when the ring 600 is fitted to the grip 400, the grip is penetrated, the shaft 500 is circumferential or longitudinal It is desirable to prevent slipping. 11B is a perspective view showing the final form in which the ring 600 of the eighth embodiment of the present invention is attached to the grip 400 of the club 2.

(Example 9)

In the above embodiments, the shape of the cavity 200 is protruded out of the grip or concave into the grip. However, the cover of the cavity concave in the above may be filled with a soft material such as cotton or sponge so as not to appear in appearance in accordance with the surface of the grip. In this case, it is better to make the edge of the cavity or the outer material relatively hard than the soft material in the cavity so that it can be felt in the right grip of the right hand. The technical gist of the present invention is to construct a pair of markers 1 on the grip 400 so that a small amount of rotational movement is smoothly performed between the right hand grip and the club 2, and in this case, the position of the umbilical finger holding the right hand It is clearly shown that the rotation is allowed through the slip at the edge of the cavity, and the virtual pin axis 270 connecting the cavity pair is responsible for the role of the axis of rotation can be said to fall within the technical scope of the present invention. have.

Next, using the grip 400 or the ring 600 having the cover pair (1) of the present invention using the golf club (2) employing the method and the effect of using the pendulum theory created by the inventor It is introduced and explained in detail.

First, the grip method of the golf club 2 is demonstrated. Two-hand grip methods in golf include interlocking, overlapping, and tenfinger. Among the right handed golfers, there are two ways to grasp the grip of the right hand. One is that the index finger of the right hand turns the grip 400 on one wheel to meet the thumb and makes a word overlap, and closes the fingers between the fingers 400 so that the grip 400 does not play at all in the right hand. It is ring-like strict posture to say. The other presses the upper surface of the grip 400 with the thumb of the right hand as shown in FIG. 3, and the index finger makes a hook like a fish hook, and walks on the lower surface of the grip 400 to apply power to both fingers. As a hook, it is a hook-like brace position that fixes the club 2 so as not to play in the right hand while bearing some of the weight of the club 2. However, the grip of the club must move somewhat within the golfer's right hand during the swing, as shown in FIG. It is not played by the grip 400 contact portion of the index finger, but a certain smooth rotational movement is surely ensured within the grip, so that the swing is accurate. In other words, if you use a grip that holds the cover pair with the right index finger, the connection between the body and the golf club's swing is smooth and secure, so the correct swing is achieved. This is explained in more detail below.

First, in the hook-shaped right hand index finger grip, the tip of the thumb and the hook of the index finger press and hold the grip 400, so that the axis connecting both fingers coincides with the pin axis line 270. Since the pin axis is parallel to the face of the club and is perpendicular to the target line, a slight right rotation of the club shaft about the right index axis of the right hand makes a takeback of the backswing parallel to the target line. As mentioned earlier, the grip should move slightly in the hand during the swing.If you take a picture of the right hand as shown in Fig. 3, both ends of the right index finger are open without touching, and there is an empty space at the root part where the index finger is split. This is possible. A small grip rotation in the hand through the marker pair leads to an accurate takeback, while a small amount of grip rotation in the right hand increases the swing arc, resulting in a significant amount of additional power at impact. For this reason, the use of the cover pair 1 of the present invention creates a natural swing motion, which improves the directionality and power at impact.

Now, the effect of the present invention will be described in more detail through the pendulum theory by the present inventors. In order to explain the technique of the present invention, the double pendulum theory is applied to a swing of a putter or a short iron, and the triple pendulum theory is applied to a swing of a driver or iron that needs to increase a large distance. Apply. The double pendulum theory explains the resonance phenomenon of the upper body of the standing posture with the two-hand grip as a medium between the swing of the body made by the rotation of the shoulder and the left arm and the swing of the club made of the club shaft. In this pendulum theory, the upper body swing created by the rotation of the shoulders and the left arm is called the secondary pendulum system, which is centered on the cervical spine (the intersection of the neck where the shoulders and the spine meet). The left arm (the right arm) is used as a vibrating arm, and both hands are pendulums. The primary pendulum system is a kinematic system with the pin axis 270 in the right hand grip as the central axis, the shaft 500 as the arm of vibration, and the club head 700 as the pendulum. A good forward swing is a case where the first vibrating system is well tuned to the swing rhythm of the second vibrating system and the first vibrating system swings quickly and has a strong force. This is a phenomenon in which resonance occurs between two swings. That is, the golf swing is a phenomenon in which the swing of the human body using the arm and the swing of the object using the club shaft are physically interfered, and the interference of the two vibration systems is made by using the grip 400 of both hands as a medium. In other words, golf is the process of accelerating the swing of the arm in the second vibration system, which is transmitted to the first vibration system through the two-hand grip, so that the swing speed of the club shaft is increased and its amplitude is enlarged. Can be said to be resonant with the vibration of the human body. In the second vibration system, the vibration center of the human body is at the cervical spine of the neck, and both hands are pendulums; In the first vibrating system, the vibration center of the object becomes a marker pair and a real or virtual pin axis 270 connecting the marker pair, and the pendulum becomes the head of the club. Therefore, the right grip grip of the right hand holding the marker pair and the pin axis 270 may serve as an important link between the two vibration systems and cause resonance.

Putting or short irons can be done only by pendulum motion of a small amplitude first vibrating system at close range, but at a longer distance, they resonate with the motion of a medium or larger amplitude second vibrating system to add power. Consider the meaning of resonance between two vibration systems. If you use the golf terminology, the backswing is called takeback and the pendulum motion of the first vibration system is called take-up, and the resonance is smoothly received at the end of the take-back and connected to take-up, which is the second vibration system. it means. In the forward swing, on the contrary, the pendulum motion of the second vibration system is called the downswing, and the pendulum motion of the first vibration system is called the impact motion.Resonance accelerates the downswing and creates a short, smooth, strong and large swing arc at the end of the impact motion. It means to make. Using this resonance, the backswing is smooth and continuous, and the forward swing is fast and large in amplitude, resulting in a powerful swing.

In order to actually implement a putting or approach shot, the technique of the present invention performs the following double pendulum motion. First, determine where to center the second vibration system with respect to the human body at the address. For example, if the distance is close, the center of the second vibrating system may be placed in the joint of the left shoulder rather than the cervical spine. When the right wrist is slightly cocked to the right as a trigger of the takeback, the shaft 500 of the club 2 rotates slightly to the right with respect to the pin axis 270 of the hand, thereby forming a first vibrating system having relative pendulum motion. The magnitude of the amplitude does not have to be very large. To this end, the oscillation is resonant, and the center of the cervical spine or the left shoulder joint, and the left arm as a rotation radius to configure a second vibrating system, the second vibration system is a common swing motion that is often used in the golf swing. When the resonant backswing is constructed like this, the reverse direction of the backswing automatically occurs in the forward swing, so that both vibrometers resonate and the direction of the ball is accurate and powerful.

Furthermore, the effect of the grip 400 of the present invention will be described with respect to a swing of a driver or the like. In the driver, spoon, and iron, a tertiary pendulum system may be added in addition to the motions of the first and second vibration systems to secure a long distance, unlike the swinging motion of the putting. At this time, the golf swing achieves the maximum triple pendulum motion to achieve the complex motion. Since the first vibration system centering on the pin axis line 270 and the second vibration system centering on the cervical spine have already been introduced, a third concept, a new concept, will be described here. The third vibration system refers to the process of moving the upper body weight to the right side with respect to the hips pushed back to make an additional distance in golf. This creates a vibrometer with the lower part of the hip, for example, the tailbone being the third axis of vibration, the spine being the third arm, and the upper body's shoulder being the third pendulum. It can be said that the spine, the oscillation radius, flexes elastically to the right in the backswing and flaps the beam springs to the left in the forward swing. This case is in the form of a reverse pendulum that is upside down in reverse to the clockwork movement. If there is a pendulum motion of the third vibrating system, the cervical spine, which is the center of the second vibrating system, is accelerated to the left in the forward swing, thereby accelerating the system of the second vibrating system, thereby accelerating the system of the first vibrating system connected to each other. In addition, since the second swing penetrates both hands, the second pendulum by downswing, which is an active rotation of both shoulders and the left arm, the system of the first vibrometer is further accelerated around the pin axis captured by the right hand index finger. . In addition to the passive system acceleration described above, the first vibration system, which occurs at a short time, releases the clubhead, which is the first pendulum, by self-acceleration such as releasing the right cock of the right wrist holding the grip to the left, and straightening the bent right arm. Acceleration creates a large impact.

In the golf swing using the present invention, first, the first vibration system is operated around the pin axis 270 in the take-back, the second vibration system is operated around the cervical spine in the take-up, and the center of the hip bone is moved in the weight shift. Start the three vibrometers. Experience has shown that the second and third vibrations may occur simultaneously. In the forward swing, the third vibration system is operated in the reverse order to move the upper body to the left, while the second vibration system rotates both shoulders to the left around the cervical spine and pulls the left arm down. The combination of the piston action and the restoring force of the beam spring to release the right wrist of the right wrist and the torsion spring restoring force of the twisted left arm and the left wrist to the left combine to accelerate the first vibration system dramatically. For this reason, the shaft of the club having the flex as the rotation radius of the first vibration system is bent due to the initial inertia force of the club head, restored at the moment of impact, and delivers explosive energy to the ball. In the case of a near-approach shot, it is effective to resonate only the first vibrometer, to resonate the first and second vibrometers in the medium range approach, and to resonate all three vibrometers in the long distance. By using the golf club 2 adopting the invention of the present patent, since the first vibrating system is reliably included in all the vibration modes described above, it is possible to use a swing that is accurate and powerful by using the club as the basis of the swing.
